6 The graph shows the motion of three swimmers during a 30-min workout. Which swimmer had
the highest average speed over the 30-min time
interval? Explain.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

c) up is the direction the magnetic force is acting on the charge.
